STAM PER-BATTERY.

SPECIFICATION forming part of Letters Patent No. 647,057, dated April 10, 1900.

Application tiled April 14, 1899. l Serial No. 713,072. (No model.)

uary 12, 1899, Serial No. 84,290) of which the following is a specification.

This invention is designed to supply an improved stamper -battery by which a given amount of ore or material can be crushed more quickly and at a much less expenditure than by present appliances.' The invention is based on the principle of providing a number of hammers pivoted near the 'periphery of a revolving wheel or a set of revolving circular plates in connection with a corresponding series of disconnected stampers suitablyV constructed and arranged in suitable boxes for the purpose of enabling the force of the revolving hammers to be effectively applied.

In order that my invention maybe clearly understood, I will describe the same with reference to the accompanying drawings, in which- Figure 1 is a side View of my improved sii-amper. The battery-box and portion ofthe bed of same are in section. Fig. 2 is a front view of the same. The hopper and portion of the front of the battery-box are removed and portion of the bed is shown in section. Fig. 3 is a plan with the upper portion of the hopper and of the main frame removed. Figs. 4f, 5, and 6 are similar views of a` battery, showing a modification of the arrangement shown in Figs. 1, 2, and 3. Figs. 7 and 8 are sectional views showing another arrangementof battery-box.

I will first describe Figs. 1, 2, and 3. The hammer-wheel 2, to which the hammers 1 are hung, may be made of one or more pieces in any convenient manner. I prefer to employ a number of circular plates connected together by suitable bolts 3, upon which the hammers are hung. This wheel is mounted on a central spindle 4, the bearings 5 of which are supported bya main frame 8. The spindle is provided with fast and loose pulleys 6 and 7 whereby it is operated by steam or other power. I have shown eighteen hammers in six sets of three, the hammers of each setbeing arranged to strike in rotation upon one Vof the stampers 10. The stainpers 10 are arranged within a specially-devised batterybox having two compartments, an upper and a lower. The bottom plate 16 extends the f ull lengthof the battery-box and is provided with apertures, one beneath each stamper, an anvil-block 23 to receive the stroke of the staxnper being fitted within each aperture.

A little above this bottom plate is an intermediate plate 17, which is provided with ap` ertures, one for each stamper. Between the Iplates is a distance piece or frame 18, which extends along the back and the two ends of the stampers and with the plates forms the lower compartment ofthe battery-box in which the ore is crushed. Above the intermediate plate`17 is a hood 19,'in the top plate of which ,are like apertures, one for each stamper. This forms the upper compartment. The two apertures-mamely, that in the top of the hood and that in the intermediate plateform guides for each stamper, through which they` are raised and depressed, crushing the ore upon the corresponding anvil-block in the bottom plate. Within the hood 19 are `springs 13, preferably spiral, one to each of the stam pers lO, whereby the stamper is lifted after the retreat of the hammer. The spring 13 encircles the stamper, the upper end of the spring fitting immediately beneath a collar 11 on the stamper and the bottom end resting upon the top of the intermediate plate 17. Each of the anvil-blocks .23 beds upon the specially-formed bed-block 2G and has at its center a downwardly-projecting stemv 24:, the bottom of which impinges upon an oscillating lever 25, pivoted in the bed-block and so adjusted that as one anvil-block is depressed to the bed-block another is raised from the bed-block. Suliicient space is left between the outside of the anvil-block and the hole in the bottom of the battery-box to allow the finely-crushed material to drop through onto the inclined surfaces of the bedblocl; 26 and its supporting-beam and thence to a shaking-sieve 32, which leads any ma- IOO terial which is too coarse for treatment to a pair of rollers 36, where it is crushed to the necessary in-eness. The anvil-block has a downwardlyprojecting circular lip fitting around the projection of the bed-block to prevent any material lodging between the anvilblock and the bed-block. The sieve 32 is supported from the main frame by chains or other connections and operated by a suitable cam arrangement 33 on the main spindle and operating-levers 34. The rollers 36 are operated by means of belts and pulleys from the main spindle 4. The hopper 30 is arranged to feed the material to the front ofthe lower compartment of the battery-box and is provided at intervals with bars 31, which regulate the How of the ore and prevent it from jamming` together.

In operation the ore is placed in the hopper 30 and passes downto the lower compartment of the battery-box to between the bottom of the stamper 10 and the top of the anvil-block 23. On the hammer-wheel 2 being rotated the hammers l are caused to fly out from the wheel, and each one of each set in rotation strikes the stamper to which it belongs, driving it downward and crushing the material beneath it. Immediately the blow has been struck the hammer rebounds toward the Ycenter of the wheel and is carried past the battery-box before it swings outward again, and the stamper islifted by the spring 13, allowinga fresh supply'of ore to fall onto the anvil-block. Vhen the stamper is driven downward, the anvil-block is caused to bed firmly on the bed-block, the stem 24 depressing one end of the oscillating lever 25, thereby lifting the anvil-block above the other end of that lever. The object of the oscillation is to prevent the crushed material lodging between the anvil-block and the aperture in the bed of the battery-box and to cause it to pass away freely. The crushed material falls down the inclined faces of the bed-block and its supporting-beam and thence onto the sieve.

The above arrangement is specially applied to dry crushing.

Referring to Figs. 4, 5, and 6, in this arrangement the springs 13 are dispensed with and in place thereof the stampers 10 are raised by means of levers 14, each of which has at one end a cheek which engages the under side of the collar 11 on the stamper, while the other end impinges upon the periphery of the wheel-plate. The periphery of the wheel-plate is specially designed and shaped to operate the levers which lift the stampers, so that when the hammer has delivered its blow on the stamper and retreated therefrom the one end of the lever is depressed by the wheel-plate raising the other and with it the stamper and thenletting it drop immediately before the strike of the next hammer. In this construction I'have shown only twelve hammers in six sets of two each. The battery-box is specially designed for wet crushing and the back and front and ends and the bottom are made in one solid casting, apertures being provided in the bottom for the anvil-blocks. The' stampers are guided and supported in apertures in an intermediate plate and the top plate of the battery-box, as inthe previous arrangement. Underneath the top of the battery-box are two pipes 20, extending from end to end, for the supply of water. The arrangementof anvil-blocks and bed-blocks and of the hopper is the same as previously described; but instead of the shaking-sieve the crushed material is delivered to amalgamating-tables or other suitable goldsaving device. Above the amalgamating-tables a floor is attached to the frame to prevent oil or other matter dropping into them. Beneath this floor is a drawer for holding tools or anything desired. The method of operation in this case is the same as that previously described, except that the stampers are lifted by the levers 14 instead of by springs.

In Figs. 7 and 8 another form of batterybox is shown. 'In place of the anvil-blocks 23, as previously described, I employ oscillating bars 28, one at the back and the other at the front of a central bed, oscillating upon projections from that central bed. The bars are placed in position from the front and from the back, the front and the back of the battery-box being hinged to open, as shown in dotted lines in Fig. 7, to enable this to'be done. The stampers 10 are supported in apertures in guide -plates, as previously described, which are secured to the ends of the stamper-boX.. In this case the crushed material passes down between the oscillating bars and the central bed-block and is discharged through slots or passages 29 in the cross-piece of the frame.

Having thus described my invention, I claim therein as new and desire to secure by Letters Patent- 1. A stamper-battery consisting of a supporting-frame, a hammer-wheel composed of a multiple of circular plates connected by bolts, a multiple of swinging hammers hung on the bolts and means for applying power to the wheel in combination with a stamperbox ot' two compartments having apertures, disconnected stampers mounted in the apertures, means for raising the stampers, oscillating anvil-blocks, and a hopper supplying ore to the anvil-blocks, asspecied.
